To e??? wwmit may concern:

lie it known that l, donn M. l/lrtson7 a ,citizen ot the United States, und resident o''f Sen Diego9 and county off San Diego, State ot' California7 have invented certain new und useful improvements in 'lobacco ilipes, oi which the following is a speciiid in a pipe always leaves a residue .l not only is disagrei-iable and harmful to the smoker, but that is e constant source annoyance und trouble due to its rapid coli tion in such quantities within the bores of the sten'is oi pipes et most commercial tyggies as to choke the stems and thereby necessitate frequent cleaning ot the seine Accordingly it has been niy purpose in producing' i'ny present improvements to provide a pipe in which the smoke is filtered and the residue therefrom collected during passage ot the smoke through the stein' oi the pipe whereby substantially all disagreeable7 harn'iiul and annoying eiects from the residue are eliminated.

idf ith the foregoing and other purposes in view my invention consists in the novel i features of construction7 combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and defined in the appended claims. l

in the drawings, wherein like characters of reference denote corresponding parts in the diiiereut views hioure l isa longitudinal'section through a pipe embodying the novel and essential.' features of my invention;

Figure 2, a side elevation;

Figure 3, top plan of the bowl portion et the pipe;

TFigure d, a detail perspective of the removable cage or holder for the filtering and residue collecting material; and

Figure 5, a section on the line 5-5 of Figure i.

Referring now to the drawings in detail, 10 designates the bowl ot my improved pipe, ll its stein and 12v its detachable inoutl'fipiece. Bowl l0 is provided with the usual tobacco chamber 13 and stem. ll is'provided with a bore 1d of large diameter that extends across the bottom of said tobacco chamber and communicates therewith through the latters somewhat restricted bottom portion l5, which portion is sub Serial No. 667,714.

stantially oi' the sinne diametcr'us bore lei as shown.

llotetubly and removably fitted within the bore lli oi stein ll' is a cage lo that preferably is pressed or stamped from a single piece o'i material such as sheet inetai and that consists oi a tubular body7 segments otP the inner end portion oi which are cut away leaving a plurality of longitudinally extending bars ii" which preferably are three in number and evenly spaced circumierentially ot the body as clearly shown in Figures t and i oi' the drawings. 'ihcse bars connect the cap-like inner end i8 oi the body with its outer unperforuted ond portion i9, and this latter portion is extended terniinaliy outward and then inward towards the other end of the body with the resultthat the cage is provided at its outer end with a thiinbie 2O that is disposed in outwardly spaced, concentric relation lwith respect to the outer end portion ot the cylindrical body as is apparent. Thiinble 2@ preferably is knurled or milled as indicated at 2l to provide a convenient finger grip t'or rotating the cage, it being observed from the showing in Figure l that the cylindrical body oit the cage is disposed entirely within the bore 14 of stein 'll7 while the thinible 2() snugly engages over the outer end ot the stein and not only provides means for rotating the cage, but serves as aseal to exclude air from bore le, in which connection l desire to point out that if necessary a suitable gasket may be placed between the outer end of the stein -11 and the portion of the cage that ovcrlies said outcrend whereby air may positively he excluded from said bore.7

Mouthpiece 12 is provided with a reduced inner end 22 that iits within the outer end portion of the cylindrical body of the cage, the smoke duct in said mouthpiece being in communication with the tobacco chamber in the bowl l0 through thc cage :ind bore i4: as is manifest,

iin the use oi' my improved pipe a suitable smoke filtering and residue collecting substance or material 23 such as commercial steel wool is placed within the cylindrical body of the cage between the inner end ot' the mouth piece 12 and the cap 18 either `prior to .or ai'ter the cage is engaged, :1s

shown in Figure 1, with the bowl and stein of the pipe, and by means of the thimble 20, the cage is rotated until one of the open spaces between adjacent bars 17 underlies the restricted bottom portion 15 of the tobacco chamber 13, in which position the material 23 constitutes the bed of the tobacco chamber. Thus it is apparent that all smoke passing from chamber 13 to the mouthpiece 12 must pass through and be filtered by the material 23 which material also acts to collect all residue such as ash, carbon, oil and nicotine as is further apparent.

Since the cylindrical body of the cage 16 is provided with plural bars 17 and an equal number of cut out spaces between said bars, rotation of the cage through a predetermined angle, in this instance 120, will dispose a new and clean part of the material 23 beneaththe tobacco chamber 13 whenever the material between a given pair of bars becomes saturated with residue. lVhen the cage has been rotated to successively dispose all ofthe spaces between the bars 17 beneath the chamber 13, 'the cage may be withdrawn from the stem, the material' 23 removed therefromv and clean material substituted.

Since the body portion of the cage .tits snugly within the bore 14, it is' manifest that rotation of the cage causes the bars 17 toact throughout their length as Scrapers which assures that all deposits will be removed from the wall of said bore and the latter as a consequence be maintained conv stantly clean.

Due to the large bore in the stem 11 and the equally large opening in the bottom' of the tobacco chamber through which the smoke passes into said bore all annoyances such as are commonly due to choking of tobacco pipes are eliminated in .my improved pipe. Furtherrnore, my improved pipe is cheal and easy to produce, strong, durable, rea ily and easily cleaned and thoroughly efficient for its purpose.

Various changes and desirable additions may bevmade-in and to my improved pipe within the spirit and scope of my invention as defined in the appended claims.

1. A tobacco pipe includingra bowl prowithin said bore and provided with means for scraping the wall of said bore when, the cage is rotated, and means disposed exteriorly of the stem for rotating said cage.

2. A tobacco pipe including a bowl pro vided with a tobacco chamber, a stem provided with a bore extending` across the. bottom of and communicating with said tobacco chamber, a cage including a tubular body portion disposed within said bore and a thimble portion fitting over said stem, said tubular body portion being segmentally cut aw ay to provide circnm'ferentially spaced bars, liltering and residue collecting material arranged within Said tubular body portion, and a mouth piece .fitted within the outer end ot' said tubular body portion.

3. A tobacco pipe including a bowl provided with a tobacco chamber, a stem )rovided with a relatively large bore extending entirely across the bottom of and intersecting s aid tobacco chamber, a mouthpiece extending from sald stem', filtering and residue collecting material arranged within said bore at 4the bottom of the tobacco chamber sol as t'o constitute a bed for tobacco contained within saidchamber, and means operable independently -o said mouthpiece while the latter is engaged with the stem to rotate the liltering and residue collecting material Within said bore, for the purpose set forth. l

In testimony whereof I hereunto affix my signature.
